Electronics Components Amplify with a Transistor Circuit Diagram Transistors can act as amplifiers while they are functioning in the active region or when it is correctly biased. We use a transistor as an amplifier when we want to amplify the input signal. The power gain of an amplifier is defined as the product of the current gain and voltage gain of the amplifier. It is also defined as the rate of This tutorial actually meant to explain the practical importance of the well known transistor theories, characteristics plots and make use of them to design a high gain amplifier circuit using a single transistor and minimum number of other components. We will analyze certain transistor characteristics and theories, summaries them, and by the end of this tutorial we will be designing a high The proposed amplifier circuit uses complementary transistors to achieve the intended high power with Hi-Fi quality. The unit is powered with a 45V + 45V supply, with current not more than 7 amps. Most of the incorporated transistors barring the BC556C must be mounted on the heatsink, which must be prferably fixed over one of the sides of the
BJT amplifier is basically a bipolar junction transistor operated in the active region. It increases the strength of the input signal and produces an amplified output. Depending upon the quantity amplified by the circuit, the BJT amplifier could be a voltage, current, or power amplifier. Types of BJT Amplifiers
